CrystalRoom 2.0 is a major release built around one idea: step inside the crystal. WALK THROUGH THE LATTICE • Full immersion: enter a room-scale crystal and walk through it • Tap any atom around you to inspect identity, coordinates, bonding, and local environment • Measure distances and angles in space, with guide lines drawn on the structure • Switch structures and scale the lattice without leaving immersion • Head-anchored toolbar keeps the essentials within reach GUIDED TOURS • A 20-step tour of the windowed workspace that teaches by doing • An interactive immersive Halite tour with hands-on tasks • “Tour This Structure”: a generated tour that adapts to whatever crystal you are viewing SEE MORE OF THE STRUCTURE • Miller planes with adjustable h, k, l, live d-spacing, presets, plane families, and offsets • Coordination polyhedra • Complete boundary coordination with display-only edge atoms • A movable crystallographic axis gizmo that mirrors every rotation • Tap a legend entry or search to highlight an element • Measurement guide lines and a measurement history in the windowed view FIVE NEW STRUCTURES • Corundum, calcite, fluorite, zircon, and forsterite, reconstructed from reference crystallographic data and validated against established tooling A MORE TRUSTWORTHY ENGINE • Full space-group symmetry expansion with special-position and disorder handling • Corrected quartz structure and space group • Chemically informed bond detection, including ionic halides • Its scientific pipeline is backed by an automated test suite covering lattice mathematics, structure parsing, published bond lengths, coordination, Miller-plane geometry, guided-tour logic, scene limits, and reference structures cross-checked against established crystallographic tooling. A BETTER WORKSPACE • Undo and redo rotation and zoom • Your structure, supercell, and view are restored when you return • Supporting windows dock around the crystal instead of in front of it • VoiceOver labels across the toolbar • Much smoother rendering of large supercells, with the biggest unit cells capped automatically to keep Vision Pro responsive Interested in custom structures or an institutional deployment?

Focused release improving app stability and performance. CIF file import has been temporarily removed while we build a more robust implementation with better support — coming in a future update. The core visualization experience with 6 built-in crystal structures remains fully featured.
